Drill Rod Tool Steels 03130 O1 Tool Steel Flat Stock

Product Description

The DRILL ROD TOOL STEELS 03130 is an O1 oil-hardening tool steel flat stock bar used in precision toolmaking, die making, and general machining applications. Conforming to AISI Type O1 specification, this flat stock measures 5/64 inches thick, 4 inches wide, and 36 inches long, with a weight of 3.22 pounds. Thickness tolerance is held to plus or minus 0.001 inches, making it suitable for applications where dimensional accuracy matters before and after heat treatment. Machinists, toolmakers, and industrial fabricators work with this material to produce punches, dies, gauges, and cutting tools.

This O1 tool steel flat stock is appropriate for general-purpose toolroom and production applications requiring an oil-hardening steel that machines cleanly in the annealed condition and responds predictably to standard oil-quench heat treatment. At 4 inches wide and 36 inches long, it provides a practical starting blank for medium-to-large flat tooling components. Width tolerance is plus 0.005 inches and minus 0.000 inches. Length tolerance is plus 0.5 inches. These tolerances are standard for hot-rolled and annealed flat tool steel stock and should be factored into layout and saw-cutting operations prior to finish machining.

Compatibility

Designed as a standard AISI O1 oil-hardening flat stock suitable for toolroom and production use wherever O1 tool steel in flat bar form is specified.

Installation Notes

Material should be handled, cut, and machined in the annealed condition prior to heat treatment. Use appropriate personal protective equipment and industrial cutting equipment when sawing to length. Heat treatment should be performed by qualified personnel following established procedures for AISI O1 tool steel, including proper preheat, austenitizing, oil quench, and temper cycles. Verify final dimensions after rough machining and before finish grinding to account for any movement during heat treat.
